  • Does CPAM reduce water adsorption density on Na-MMT surface?
  • The adsorption of CPAM reduces highly the amount of water adsorption density on Na-MMT surface than PAM and APAM. CPAM adhesion is high and more accelerated by the positive charge of its molecules with the negative charge of Na-MMT. Polymer molecules adsorption reduces the vertical distance between polymer and the surface of MMT particles.
  • What are the adsorption characteristics of Apam and CPAM molecules?
  • Including the adsorption characteristics of PAM, APAM and CPAM. The simulation results show that PAM and APAM molecules have low adsorption density on Na-MMT surface compared to CPAM molecules. PAM and APAM molecules interact more through h-bonding with their own molecules leading to a weak interaction with Na-MMT particles.
  • Is CPAM better than Apam?
  • Contrary to APAM, CPAM shows a good adsorption performance on the montmorillonite surface. However, the configuration of the adsorption layer changes with the variation of the polymer ionicity. Moreover, CPAM is concentrated at 3 Å from the surface of the montmorillonite. Regarding the 12.5% ionicity, a tight adsorption layer of the CPAM is formed.
  • Does CPAM reduce water adhesion?
  • CPAM reduced water adhesion highly than PAM followed by APAM. Controlling the number of CPAM molecules affect and reduce more the adsorption percentage of water in the system. Comparatively to PAM and APAM, CPAM can weak more the hydration of Na-MMT and could achieved good inhibition;
